I was trying to select an image from a device folder but it an error in the logcat like this:

This error doesn't always come out and sometimes it changes, but it's always about running out of memory
This is the code with which I choose an image in the gallery:
public void inserimentoImmagine() {
addImage = findViewById(R.id.aggiuntaFoto);
addImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
if (ActivityCompat.checkSelfPermission(AggiuntaAnimaleManuale.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(AggiuntaAnimaleManuale.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, PICK_FROM_GALLERY);
} else {
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, PICK_FROM_GALLERY);
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
#Override

super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case PICK_FROM_GALLERY:

if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, PICK_FROM_GALLERY);
} else {
//do something like displaying a message that he didn`t allow the app to access gallery and you wont be able to let him select from gallery
}
break;
}
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_FROM_GALLERY && resultCode == RESULT_OK) {
if (data == null) {
//Display an error
return;
}
Uri imgUri= data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor=getContentResolver().query(
imgUri, filePathColumn, null, null, null
);
String picturePath;
Bitmap bitmap;
if (cursor != null && cursor.moveToFirst()) {

I'm making and android app where I need two upload images and save them to server.
When I select it from the first button, it is appeared in the second but I need two different images.
photoUpload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chooseImage();
}
});
photoUpload2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chooseImage();
}
});
}
private void chooseImage() {
Intent openGalleryIntent = new Intent();
openGalleryIntent.setType("image/*");
openGalleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(openGalleryIntent, "Select Picture"), GALLERY_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_REQUEST_CODE && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
imageView.setImageBitmap(bitmap);
imageView2.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
You are getting this because you are setting selected image to imageview 1 and 2. to solve this you can use different request codes or use Boolean variable to differentiate the uploading of image 1 and 2
Define two Boolean variable to differentiate the uploading of image 1 and 2
Boolean first = false, second = false;
#Override
public void onClick(View v) {
first = true;
chooseImage();
}
});
photoUpload2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
second = true;
chooseImage();
}
});
}
private void chooseImage() {
Intent openGalleryIntent = new Intent();
openGalleryIntent.setType("image/*");
openGalleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(openGalleryIntent, "Select Picture"), GALLERY_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_REQUEST_CODE && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
if(first)
{
imageView.setImageBitmap(bitmap);
first = false;
}else if(second)
{
imageView2.setImageBitmap(bitmap);
second = false;
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
You can use library to select multiple images from Gallery. There are many libraries that are available, one such is https://github.com/ParkSangGwon/TedPicker
Hope this will help you!
Happy Coding
You are setting same image to both ImageViews.
Change Your Code to
photoUpload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chooseImage(GALLERY_REQUEST_CODE_1);
}
});
photoUpload2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chooseImage(GALLERY_REQUEST_CODE_2);
}
});
}
private void chooseImage(int requestCode) {
Intent openGalleryIntent = new Intent();
openGalleryIntent.setType("image/*");
openGalleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(openGalleryIntent, "Select Picture"), requestCode);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_REQUEST_CODE_1 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
imageView.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
if (requestCode == GALLERY_REQUEST_CODE_2 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
imageView2.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
I think you have to set same bitmap in both imageView
You should try bellow code
boolean isFromFirstBtn;
photoUpload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
isFromFirstBtn = true;
chooseImage();
}
});
photoUpload2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
isFromFirstBtn = false;
chooseImage();
}
});
}
private void chooseImage() {
Intent openGalleryIntent = new Intent();
openGalleryIntent.setType("image/*");
openGalleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(openGalleryIntent, "Select Picture"), GALLERY_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_REQUEST_CODE && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
if(isFromFirstBtn){
imageView.setImageBitmap(bitmap);
}else{
imageView2.setImageBitmap(bitmap);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
When trying to compile Android studio code I get the following error: array dimension missing
error: array dimension missing
public void showCamera(View view) {
if (checkSelfPermission(Manifest.permission.CAMERA) ==PackageManager.PERMISSION_GRANTED) {
showCameraPreview();
}else {
if (shouldShowRequestPermissionRationale(Manifest.permission.CAMERA)){
Toast.makeText(this, "Camera permission is needed to show the camera preview.",
Toast.LENGTH_SHORT).show();
}
requestPermissions(new String[]Manifest.permission.CAMERA), REQUEST_CAMERA);
}
}
}
you can try this
public void showCamera(View view){
ActivityCompat.requestPermissions(
MainActivity.this,
new String[]{Manifest.permission.CAMERA},
CAMERA_REQUEST );
}
then you need override onRequestPermissionsResult
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if(requestCode == CAMERA_REQUEST){
if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
callCamera();
}else {
Toast.makeText(getApplicationContext(), "Camera permission is needed to show the camera preview.", Toast.LENGTH_SHORT).show();
}
return;
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
fun calCamera()
public void callCamera()
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_REQUEST);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 0);
intent.putExtra("aspectY", 0);
intent.putExtra("outputX", 250);
intent.putExtra("outputY", 200);
}
and override ononActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK && data != null) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
super.onActivityResult(requestCode, resultCode, data);
}
the problem when I click on Button choose a contact and choose a contact not call the number, I want when choosing a Number phone call Directly
buttoncontact = findViewById(R.id.choosecontact);
public void choosecontact1 (View view){
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
startActivityForResult(intent, PICK_CONTACT)
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
String call = buttoncontact.getText().toString();
if ((requestCode == 1) && (resultCode == RESULT_OK)) {
Cursor cursor = null;
try {
Uri uri = data.getData();
cursor = getContentResolver().query(uri, new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER }, null, null, null);
if (cursor != null && cursor.moveToNext()) {
String phone = cursor.getString(0);
// the Problem on that code
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(String.valueOf("tel:" + CONTENT_TYPE)));
// i want open phone contact and call directly
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
startActivity(intent);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
What is "CONTENT_TYPE"? Shouldn't it be the phone string you just get?
intent.setData(Uri.parse("tel:" + phone));
Add permission in manifest file :
Make function of calling phone number
private static final int CALL_REQUEST = 100;
private void callPhoneNumber(){
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(ProfileActivity.this, new String[]{Manifest.permission.CALL_PHONE}, CALL_REQUEST);
return;
}
}
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:9879879879" ));
startActivity(callIntent);
}
Above api level 23, need to ask runtime permission of call and if user allow it, it will go in below method :
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults)
{
if(requestCode == CALL_REQUEST)
{
if(grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
callPhoneNumber();
}
else
{
Toast.makeText(ProfileActivity.this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
}
}
i want user Email id via AccountPicker.newChooseAccountIntent. i want Detect User Cancel AccountPicker dialog
here is a code
private static final int REQUEST_CODE_EMAIL = 1;
private TextView email = (TextView) findViewById(R.id.email);
try {
Intent intent = AccountPicker.newChooseAccountIntent(null, null,
new String[] { GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE }, false, null, null, null, null);
startActivityForResult(intent, REQUEST_CODE_EMAIL);
} catch (ActivityNotFoundException e) {
// TODO
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_EMAIL && resultCode == RESULT_OK) {
String accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
email.setText(accountName);
}
}
There is also a RESULT_CANCELED or RESULT_CANCEL constant in an Activity.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_EMAIL && resultCode == RESULT_OK) {
String accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
email.setText(accountName);
} else if(requestCode == REQUEST_CODE_EMAIL && resultCode == RESULT_CANCELED) {
Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show();
}
}
